Embodiment 1
[0049] The preparation method of a preparation for inhibiting soil nitrogen loss in this embodiment: the mass percentage is: 24% of 2-chloro-6-trichloromethylpyridine, 1% of hydroquinone, 15% of auxiliary agent, and 60% of solvent as raw materials , that is, 25kg castor oil polyoxyethylene ether, 25kg triphenylethylphenol polyoxyethylene ether, 25kg alkylphenol formaldehyde resin polyoxyethylene ether and 75kg calcium dodecylbenzenesulfonate, put into 1000L heating and cooling clamps in turn Add 600kg of xylene to the glass-lined reactor with a stirring device, stir and mix thoroughly, then add 10kg of hydroquinone and 240kg of 2-chloro-6-trichloromethylpyridine to the mixture, and heat to 50 At about ℃, at this temperature, stir and keep warm for 1 hour, and cool to room temperature to obtain a light yellow and transparent liquid preparation that can inhibit soil nitrogen loss. The process is simple and the operation is convenient. The preparation is used to suppress the loss...
Embodiment 2
[0051] The preparation method of a preparation for inhibiting soil nitrogen loss in this embodiment: the mass percentage is: 20% of 2-chloro-6-trichloromethylpyridine, 5% of hydroquinone, 15% of auxiliary agent, and 60% of solvent as raw materials , that is, 25kg castor oil polyoxyethylene ether, 25kg triphenylethylphenol polyoxyethylene ether, 25kg alkylphenol formaldehyde resin polyoxyethylene ether and 75kg calcium dodecylbenzenesulfonate, put into 1000L heating and cooling clamps in turn In the glass-lined reactor with sleeve and stirring device, put 600kg C 9 Aromatic hydrocarbons, fully stirred and mixed, then added 50kg hydroquinone and 200kg 2-chloro-6-trichloromethylpyridine to the mixture, and heated to 50°C±2°C while stirring. Stir and incubate at this temperature for 1 hour. After cooling to normal temperature, a light yellow transparent liquid preparation capable of inhibiting soil nitrogen loss can be obtained. The process is simple and the operation is convenie...
